Project Description:

Nymph is a patent-protected open-flow turbine in early-stage development by Caledonia Green Innovation (“CGI”).  The concept is simple: you just moor in flowing water, it turns around and generates energy. No damns, no pipes, no civil engineering, no fuss.

The Nymph turbine is essentially a traditional water wheel turned on its side and submerged beneath the surface of the water. The blades are articulated so as to change the profile that they present to the water as the impeller rotates. The unit floats on two pontoons and the generator is mounted on the top, so it is easily accessed and out of the water.

The Nymph as the following characteristics:

•                it has low environmental impact:

−  it does not require expensive, carbon intensive civil works, and
−  it turns at the same speed as the stream, so it is fish friendly;

•                it does not dam the river, so permitting and navigation are simple;

•                it is quick to install – simply moor it and plug it in; and

•                it floats on the surface of the water, so it is easily maintained and all the electrical equipment is out of the water.

It is also designed to be cost-efficient and it is expected to be competitive with electricity generated from fossil fuels in locations with strong flows.  This makes it independent of subsidy regimes, and a desirable generation alternative in its own right.


Bainton Capital’s Role:

Screen Shot 2013-11-12 at 08.14.18Bainton Capital inserted an interim CEO and supported the business through its early stages.  Interim funding was raised, patent applications made in selected jurisdictions, branding was created and trademarked, and the technology further developed, both in its design and its commercial application.  Research and test marketing were carried out, establishing an extended market proposition for the technology – expanding from power generation to also include irrigation pumping and reverse-osmosis water purification.  Initial clients and test sites were identified internationally.  A research partnership was established with Cranfield University.

A full financial analysis, including the economics of applying the technology in different parts of the world under differing operational and regulatory regimes was carried out and Bainton Capital established potential technology partners in Asia, Africa and Latin America.  Finally,  Bainton Capital secured an offer of development funding from Brazil.  The technology is currently being further developed.
